Product design and material selection
Material grade alone does not establish a complete valve specification. Confirm the pressure boundary, seats, stem, bore, end connections and actual project conditions before selecting a construction.
Technical selection checklist
| Design requirement | Double Block and Bleed Ball Valve refers to double block and bleed isolation arrangement. For an inquiry specifying Zirconium 702, the construction and the material must be reviewed independently. Single-ball DBB and double-ball DBB designs are not automatically interchangeable. |
|---|---|
| Material-grade review | Zirconium 702 belongs to the titanium & zirconium keyword family in the supplied directory. Confirm the grade, relevant wrought or cast standard, oxidation/corrosion limits and the exact pressure boundary construction. |
| Engineering checklist | For this valve construction, check isolation arrangement, seat philosophy, cavity bleed position and applicable DBB/DIB requirements. For this material family, Validate chemistry, alloy designation, fabricability and service-specific corrosion risk. |
| Application and selection | Possible selection context: isolation points requiring a specified block-and-bleed scheme. Final suitability cannot be determined from material grade and valve design keywords alone. Confirm the process medium, size, differential pressure, temperature, bore and valve performance requirements. |
| Documents to request | Request the drawing, technical datasheet, material bill of materials, end connection, seat construction, proposed tests, material certification and actuator details when relevant. Grade-specific availability and test conditions must be confirmed by a formal quotation. |
Information required for quotation
Send your RFQ, datasheet or MTO with the required ASTM or UNS material, nominal size, pressure class, end connection, seat material, design temperature, fluid service and quantity. Include inspection and document requirements if specified by your project.
Frequently asked questions
Does Zirconium 702 automatically qualify this valve for a corrosive service?
No. Grade, temperature, pressure, medium chemistry, seat and trim materials all require review.
Can Zirconium 702 Double Block and Bleed Ball Valve be ordered in any ASME pressure class?
Not by assumption. Size, pressure class, end connections and actual design availability must be confirmed.
